I’ve been very satisfied with the ones I have from CTEK as another alternative.

Living in Wisconsin I generally garage my 2003 Bird during winter. I start it and run it in the driveway to keep the battery charged. Over the 22 years I’ve owned the car, the battery has completely drained a couple of winters. Both times, I used a smart charger to resurrect power but both times I had to disconnect the battery terminal from both positive and negative cables before the charger did its thing. This year I want to connect a trickle charger for the winter but I’m afraid the charge won’t take unless I disconnect the leads. What might I be doing wrong?

I am a new 2002 Tbird owner. I searched previous threads and found the one unit mentioned as being popular is no longer available. Does anyone use a unit they would highly recommend?

I had a couple of the Battery Tender maintenance chargers go bad within a few months so I would cross them off my list. I have a couple Harbor Freight ones, the roughly $35 versions, 4 amp, which seem to work ok. I have a Schumacher 2 or 3 amp one that I think it probably the best and smartest that I have been using most recently on one of my cars. The one I like the best overall is a 4 or 5 amp "Type S" brand.. they are harder to find, you may need to buy directly... I like it a lot because its display rotates between showing the voltage and showing the amps. All of them will at least do both regular batteries and AGM batteries. They all claim to be "smart" yet each seems to have a different idea of what the correct final voltage is, some seem to float at 13+ and others at a bit below 12. The all come with wiring you can use to make a permanent battery connection with an easy connect/disconnect. I have done that on all my cars so I connect and disconnect them quickly without opening the hood by sticking the connection in the grill/just behind the grill where I can easily fish it out. It needs to be well connected to the battery so the charger gets an accurate voltage reading. Poor connections make the readings off and then it can't tell what the true battery voltage is.

I have never had a problem trickle charging batteries connected in the car. I have had issues trying to charge (trickle or otherwise) batteries that were completely dead. If your batteries in the car were more or less "good" and had at least a remaining voltage of over 11 seems like they should have charged. Perhaps in the car the parasitic draw was lowering the voltage just a little too much and when you removed them to charge it went up just enough to let the charger work.
